摘要

高温镍基合金多层多道焊过程中，由于多重热循环作用，易于在焊缝内部产生高温失塑裂纹，在应用中存在安全隐患，在核电结构应用中尤其重要。针对该问题，本研究基于多重热循环中的温度因素，开展高温镍基合金多层多道焊实验与数值模拟研究，基于开裂区域多重热循环仿真温度数据结果，探索多层多道焊焊缝开裂区多重热循环在高温镍基合金脆性温度停留与裂纹开裂情况的关系，从而确定基于仿真热循环数据的开裂判据。首先，基于单道焊实验与数值模拟，验证仿真模型；其次，开展多层多道焊实验与模拟，通过实验开裂位置点确定仿真数据提取点，获取开裂处温度特性。基于以上研究，最终获取在实验构件边缘位置附近，脆性温区停留71.7~88.1 s，是高温镍基合金开裂敏感区。本研究提供一种基于仿真温度判定高温镍基合金裂纹的技术手段。

Abstract

During the multi-layer multi-pass welding process of high-temperature nickel-based alloys

the action of multiple thermal cycles readily induces ductility-dip cracking (DDC) within the weld metal. This poses potential safety hazards during service

and is of particular importance in applications for nuclear power structures. To address this issue

this study

focusing on the temperature factor within these multiple thermal cycles

conducted experimental and numerical simulation research on multi-layer multi-pass welding of high-temperature nickel-based alloys. Based on simulated thermal cycle temperature data for the cracking region

the relationship between the dwell time within the brittle temperature range (BTR) of the alloy and crack initiation in the multi-layer multi-pass weld cracking zone was investigated

thereby establishing a cracking criterion derived from the simulated thermal cycle data. Firstly

single-pass welding experiments and numerical simulations were performed to validate the simulation model. Secondly

multi-layer multi-pass welding experiments and simulations were conducted; simulation data extraction points were determined based on experimentally identified crack locations

enabling the acquisition of temperature characteristics associated with cracking. Based on this research

it was ultimately determined that a dwell time between 71.7 s and 88.1 s within the brittle temperature range

occurring near the edge region of the test component

constitutes a susceptibility zone for cracking in high-temperature nickel-based alloys. This study provides a technique for crack susceptibility assessment in high-temperature nickel-based alloys based on simulated temperature data.
